1.95 x 10^6 – 3.2 x 10^4 = 1.95 x 1,000,000 - 3.2 x 10,000 = 1,950,000 - 32,000 = 1,918,000

To subtract these numbers, we first need to make sure they have the same exponent.

1.95 × 10^6 - 3.2 × 10^4 can be written as:

(1.95 × 10^6) - (0.32 × 10^5)

Since 10^6 is 10 times larger than 10^5, we can multiply 0.32 × 10^5 by 10 to make the exponents the same:

(1.95 × 10^6) - (0.32 × 10^5 × 10)

Now we can perform the subtraction:

= (1.95 × 10^6) - (3.2 × 10^5)

To subtract them, we can arrange the numbers in scientific notation and subtract the coefficients:

= (1.95 - 3.2) × 10^6

= (-1.25) × 10^6

Therefore, 1.95 × 10^6 - 3.2 × 10^4 = -1.25 × 10^6.

To subtract two numbers written in scientific notation, you need to make sure that the exponents of the numbers are the same. In this case, you have:

1.95 x 10^6 - 3.2 x 10^4

To make the exponents the same, you need to adjust the second number by moving the decimal point. Since you are subtracting, you will need to subtract the numbers after adjusting.

First, let's adjust 3.2 x 10^4. The exponent in 3.2 x 10^4 is 4, while in 1.95 x 10^6, it is 6. To make the exponents the same, we need to adjust 3.2 x 10^4 to 10^6.

To move the decimal point from 4 to 6, we need to move it two places to the right. So 3.2 x 10^4 becomes 0.032 x 10^6.

Now, we can subtract:

1.95 x 10^6 - 0.032 x 10^6

Since the exponents are the same, we can subtract the coefficients:

1.95 - 0.032 = 1.918

The final answer in scientific notation is:

1.918 x 10^6
